Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a foldable shift lever device for automatic transmissions, and more specifically, to a foldable shift lever device for an automatic transmission, and more specifically, a shift lever device for a floor shift type of an automobile etc. that can be bent at a predetermined position. This invention relates to a foldable shift lever device for an automatic transmission configured as follows.

[Conventional technology]

2. Description of the Related Art In recent years, so-called floor shift type shift levers, in which the shift lever of an automatic transmission is disposed on the vehicle floor, have become popular in automobiles and the like. A shift lever that stands upright from the vehicle floor inside the vehicle cabin is used to switch gears of the automatic transmission via a remote control link system (control cable, etc.).

In automobiles and the like equipped with this floor shift type shift lever, the driver often gets in and out of the vehicle from the passenger seat in places where parking spaces are narrow or where traffic is heavy. In this case, when moving from the driver's seat to the passenger's seat, or from the passenger's seat to the driver's seat, the shift lever, which stands upright from the vehicle floor, becomes a protrusion that gets in the way, making it difficult to move from the driver's seat to the passenger's seat.

Therefore, the shift lever conventionally installed on the vehicle floor was divided into upper and lower parts, and the two parts were connected with a pin to make the shift lever bendable. This made it easier to change seats. type shift lever device (for example, Utility Model 56-
32887) has been proposed.

[Problem that the invention seeks to solve]

However, in the conventionally proposed folding shift lever device for an automobile transmission, the shift lever is bent and folded in the gear shift operation direction (vehicle longitudinal direction) when the seat is moved. Moreover, no means is taken to restrict the bending operation position of the shift lever.

For this reason, when the shift lever is bent toward the front of the vehicle and laid down, the tilted shift lever tends to get in the way, especially in cab-over type vehicles.
Furthermore, when the shift lever is bent toward the rear of the vehicle and laid down, it tends to interfere with the parking brake lever, making it impossible to lower the shift lever to a sufficiently low position, and the shift lever tends to get in the way. Also,
When the shift lever is bent, the bent portion is exposed and forms a protrusion, and it is conceivable that clothing may be caught on the bent portion when moving the seat in the vehicle interior.

Furthermore, due to the bending structure, the height of the shift lever when the shift lever is tilted and the length of the lever protruding from the cover in the direction of tilting the lever are uniquely determined. For this reason, if a folding shift lever device is applied to a car model with a different seat or vehicle floor configuration, the structure of the shift lever must be significantly changed, and the Difficult to adapt between vehicle models.

Therefore, an object of the present invention is to make the shift lever that is folded and folded down less obstructive when the seat is moved, and also to be easily compatible with vehicle models having different seat and vehicle floor configurations. It is in.

[Means for solving problems]

Therefore, the present invention adopts the following configuration as a means for solving the above-mentioned problems.

That is, the present invention makes it possible to bend the two-divided upper lever portion in one direction substantially perpendicular to the direction of the gear change operation only when the upper lever portion is shifted to the parking range, and also to separate the shift lever's gear change operation rotation center and the bending rotation center, The bending rotation center and the vertical axis center of the upper lever portion are offset from each other.

Specifically, referring to FIGS. 1 and 2 as examples, the folding shift lever device for an automatic transmission has a shift lever 10 that is disposed substantially upright from the vehicle floor and a shift knob 11 side. It is divided into two parts, an upper lever part 12 and a lower lever part 13 on the transmission side.
are foldably connected.

The bending direction of the upper lever part 12 is substantially perpendicular to the shift lever gear change operation direction, and the upper lever part 12 is attached only in the parking range to a cover 15 that is fixed to the vehicle floor side and covers the bent part of the shift lever. A bending guide groove 51 is provided that allows bending in one direction.

Further, the shift operation rotation center X-X and the bending rotation center Z-Z of the shift lever 10, and the bending rotation center Z-Z and the upper lever portion 12.
Offset the vertical axis center O-O of l ₁ and l ₂ respectively.
It is arranged as follows.

[Effect]

According to the above-mentioned means, in a shift position other than the parking range, the upper lever portion 12 of the shift lever 10 and the bending guide groove 5 of the cover 15
1 do not match, and the bending operation of the shift lever 10 is prevented.

When the shift lever 10 is bent and pushed down, the operation is as follows.

First, shift the shift lever 10 to the parking range. At this shift position, the upper lever portion 12 of the shift lever and the bending guide groove 51 are aligned, and the shift lever becomes a bendable position.

Next, fold the upper lever part 12 into the guide groove 5.
1 in a predetermined direction that is substantially orthogonal to the direction in which the shift lever is operated. At this time, a part of the upper lever part 12 is inserted into the bending guide groove 51 of the cover.
Go inside. Then, with this shift lever in the bent state, the driver's seat is moved, that is, from the driver's seat to the passenger's seat, or from the passenger's seat to the driver's seat.

In addition, by placing the upper lever portion 12 in an upright state along the bending guide groove 51 of the cover, the shift lever 10 is returned to its original state.

In this way, the shift lever 10 can be bent only when the shift lever 10 is shifted to the parking range. Moreover, the bending direction is restricted to one predetermined direction by the bending guide groove 51 of the cover.

Furthermore, since the above two types of offsets l ₁ and l ₂ are set, the height l ₃ of the shift lever 10 when it is bent and laid down and the length of the lever protruding from the cover 15 in the tilting direction can be adjusted. Can be set freely.

The figure shows an enlarged sectional view taken along line V-V in FIG. 4. For convenience of explanation, FIG. 1 shows the shift lever shifted to the parking range.

Reference numeral 10 indicates the entire shift lever, which is disposed substantially upright from the vehicle floor (not shown). As will be described later, the shift lever 10 is divided into two parts, an upper lever part 12 on the shift knob 11 side and a lower lever part 13 on the transmission side, both of which are foldably connected by a coupling means 14. . A cover 15 covers the bent portion of the shift lever 10, and in this embodiment, it also serves as a detent plate for regulating the shift position of the shift lever 10. A shift lever boot 16 prevents water, mud, dust, etc. from entering the vehicle interior, and also blocks noise from outside the vehicle interior. A support bracket 17 is attached with bolts and nuts to a chassis frame cross member (not shown) fixed to a vehicle frame, and supports the shift lever 10 so as to be rotatable in the longitudinal direction of the vehicle. A pair of upright portions 18 are formed on both sides of the support bracket 17, as shown in particular in FIG. A spacer 19 into which the shift lever boot 16 fits and the detent plate 15 are disposed on both outer sides of this upright portion 18, and one bolt 20 passes through these holes to attach a spring washer 21. It is fastened to the nut 22 via the nut 22. A collar 2 is attached to the outer periphery of the bolt 20 located on both sides of the upright portion 18 of the support bracket.
3 and a pair of resin flanged bushes 24, 24, a pipe-shaped rotating shaft 25 is provided at the lower part of the shift lever 10 and is arranged concentrically. This allows the shift lever 10 to move along the axis X of the bolt 20.
-X is rotatable in the left and right directions on the paper of FIG. The shifting positions of the shift lever 10 are from the front of the vehicle to parking range (P range),
A reverse range (R range), neutral range (N range), drive range (D range), second range (2 range), and low range (L range) are arranged in a line.

Further, a bevel gear 26 is fixed to the pipe-shaped rotating shaft 25 by means such as welding, caulking, press-fitting, or the like. A lower bevel gear 27 that meshes with the upper bevel gear 26 is rotatably mounted on a fixed shaft 28 welded to the upper surface of the support bracket 17 with a nut 29. A control lever 30 is welded to the lower bevel gear 27 and is rotatable about the axis Y-Y of the fixed shaft 28. 31 is a resin flanged bush interposed between the fixed shaft 28 and the lower bevel gear 27. Furthermore, the control lever 30
A pin 32 is welded to the tip of the control cable 34, and an end 35 of a control cable 34 is fitted onto the pin 32 via a rubber bushing 33. The pin 32 is prevented from coming off by a washer 36 and a split pin 37 provided at the tip thereof. As a result, the rotational movement of the shift lever 10 around the axis XX is converted into the rotational movement of the control lever 30 around the axis YY by the pair of bevel gears 26 and 27, and the control cable 34 is moved in the longitudinal direction of the vehicle. The automatic transmission is configured to perform reciprocating motion to switch the automatic transmission to a predetermined gear position.

Further, as particularly shown in FIG. 4, the detent plate 15 is formed with a step-shaped cam hole 38 for regulating the shift position of the shift lever 10, which will be described later. This detent plate 15 is attached together with the shift lever boot 16 to brackets 39 and 40 welded to the support bracket 17 using four screws 41 and nuts 42. The upper end of the shift lever boot 16 is fitted onto the shift lever 10.

Now, the shift lever 10 has an upper lever part 12 on the shift knob 11 side and a lower lever part 1 on the transmission side.
It is divided into two parts. And both lever parts 1
2 and 13 are connected by a joint means 14 so as to be bendable in a direction (vehicle width direction) substantially orthogonal to the shift lever speed change operation direction.

That is, as shown in FIG. 3 in particular, the coupling means 14 has a pipe-shaped rotating shaft 43 welded to the lower end of the upper lever portion 12. On the other hand, a fork-shaped housing 44 is welded to the outer periphery of the pipe-shaped rotating shaft 25 constituting the lower lever portion 13. One bolt 45 passes through the hole in the housing 44 and attaches to the spring washer 46.
It is fastened by a nut 47 via. The pipe-shaped rotating shaft 43 is concentrically arranged on the outer periphery of the bolt 45 via a collar 48 and a pair of resin flanged bushes 49, 49, and the upper lever portion 12 rotates the axis Z-Z of the bolt 45. It is configured to be rotatable around the center. Further, a torsion spring 50 is wound around the outer periphery of the pipe-shaped rotating shaft 43, and its intermediate portion and both ends are engaged with the upper lever portion 12 and the housing 44 on the lower lever portion side. The torsion spring 50 urges the upper lever portion 12 in the direction of the plane of the paper in FIG. 1 (the shift lever bending direction).

Further, the detent plate 15 is formed with a bending guide groove 51 that is continuous with the cam hole 38 and is elongated in one direction substantially perpendicular to the shift lever speed change operation direction at a position corresponding to the P range. In this embodiment, it is provided only on the passenger seat side.

A lock lever 52 is provided in the middle of the bending guide groove 51 to prevent the upper lever portion 12 from bending, and as shown in FIG. Positioning claw 54 at a position away from
are integrally provided. And the rotating shaft 53
is penetrated through the hole 55 of the detent plate 15,
A release knob 56 is attached to its upper end.
Furthermore, this release knob 56 and detent plate 1
A compression coil spring 57 that also serves as a torsion spring is installed between the lock lever 52 and the rotation shaft 5.
It can rotate around 3. And Figures 4 and 5
In the lock position shown in the figure, the pawl 54 of the lock lever 52 engages in a positioning hole 58 formed in the detent plate 15. Further, in the unlocked position shown by the imaginary line in FIG. 4 when the release knob 56 is pushed down, the lock lever 52 comes into contact with a stopper 59 on the inner surface of the detent plate 15 due to the spring force of the spring 57. Reference numeral 60 denotes a stopper provided on the inner surface of the detent plate 15 to set the locking position of the lock lever 52. In addition, the lock lever 52
functions as a part of the detent plate 15 during normal operation when the shift lever 10 is not tilted.

Regarding the cam hole 38 shown in FIG. 4, the cam hole 38 is formed in a step shape extending in the direction of shift lever operation, and the end surface of the cam hole 38 on the passenger seat side (lower end surface in FIG. 4) The upper lever portion 12 is biased by the spring force of the torsion spring 50. The N range, D range and 2 range are obtained on the same side, and the R range and L range are obtained by moving the shift lever 10 around the axis Z-Z toward the driver's seat (upper part of Figure 4). At the operated position, the P range can be obtained by simultaneously moving the shift lever 10 further toward the driver's seat side. In addition,
62, 62 are parallel surfaces formed on the outer circumferential surface of the upper lever portion 12, and are parallel to the step-like stepped portion 6 of the cam hole 38.
1 to accurately set the gear shift position. Further, 63 is an arcuate groove formed on the side surface of the cam hole 38 corresponding to the N range, the D range, and the 2 range, and can give a sense of moderation to the speed change operation of the shift lever 10.

Further, as shown in FIG. 1, the axis XX, which is the center of rotation for the shift operation of the shift lever 10, and the axis Z-Z, which is the center of rotation of the shift lever ₁₀ , are offset by l1. Moreover, the axis Z-Z, which is the center of bending rotation, and the upper lever part 1
The axis O--O which forms the center of the vertical axis of 2 is offset by _l2 .

In the foldable shift lever device for an automatic transmission configured as described above, the shift lever 10 is operated around the axis Z-Z along the cam hole 38 of the detent plate 15, and the shift lever 10 is operated around the axis Z-X. to operate. As a result, a pair of bevel gears 2
6 and 27, the control lever 30 is rotated around the axis Y-Y, and the control cable 34 is reciprocated in the longitudinal direction of the vehicle, thereby operating the manual valve lever of the automatic transmission (not shown) to a predetermined position. Switch to gear. When shifted to the P range, the upper lever portion 12 is moved into the bending guide groove 51 by the spring force of the torsion spring 50 to lock the locking lever 5.
It stops at the position where it touches 2. The lock lever 52 is maintained in its locked state because its claw 54 engages with the positioning hole 58 of the detent plate 15.

When folding the shift lever 10,
It is operated as follows.

First, the shift lever 10 is shifted to the P range. At this shift position, the upper lever portion 12 of the shift lever and the bending guide groove 51 provided in the detent plate 15 align, and the shift lever becomes a bendable position. However, the shift lever bending operation is blocked by the lock lever 52.

Next, push down the release knob 56 of the lock lever against the spring 57, and then the lock lever pawl 54 and the positioning knob 5 of the detent plate
8 and the lock lever 52 is released from its locked state. At this time, the lock lever 52 is held at a position where it contacts the stopper 59 of the detent plate.

When the lock lever 52 is released from the locked state, the spring force of the torsion spring 50 on the shift lever side moves the upper lever portion 12 along the axis Z-
It is bent along the bending guide groove 51 centering on Z, and stops at a position where it abuts against the lower end surface of the bending guide groove 51.

Then, in this shift lever folded state (shift lever tilted state), the driver's seat is moved, that is, from the driver's seat to the passenger seat, or from the passenger seat to the driver's seat.

Further, in order to return the shift lever 10 to its original state, it is operated as follows.

First, reverse the above operation procedure by pressing the upper lever part 12.
, the detent plate 15 is centered around the axis Z-Z.
along the bending guide groove 51 against the torsion spring 50 to stand upright.

Next, turn the lock lever release knob 56 clockwise until the lock lever 52 hits the stopper 60. Then, the lock lever 52 releases the spring 57.
The claw 54 of the lock lever engages with the positioning hole 58 of the detent plate, and the lock lever 52 is in the locked state, so that the normal shift lever is in the upright position.

Therefore, according to this embodiment, the shift lever 1
Since the 0 is bent in a direction substantially perpendicular to the direction of the gear change operation, that is, in the vehicle width direction, the seat can be easily moved within the vehicle interior.

In particular, as shown in FIG. 11, in a cab-over type car, the shift lever 10 is bent toward the passenger's seat, so the shift lever 10 does not get in the way when moving from the driver's seat to the passenger's seat.
It is extremely easy to move seats. Note that D represents the driver's seat, E represents the passenger's seat, F represents the vehicle floor, and H represents the steering wheel.

Furthermore, since the shift lever 10 can only be bent when shifted to the P range, in the unlikely event that the shift lever 1 is bent while the engine is running while the vehicle is stopped.
Even if the user leaves the driver's seat by tilting down the driver's seat or accidentally touches the shift lever 10 while moving the seat, there is no risk that the vehicle will start moving unexpectedly, making it safe.

Moreover, the axis XX, which is the rotational center of the gear shift operation of the shift lever 10, the axis Z-Z, which is the bending rotation center, and the axis Z-Z, which is the bending rotation center, and the axis forming the vertical axis center of the upper lever part 12. By selecting these two types of offset amounts l ₁ and l ₂ , the lever height l ₃ (axis line X-X and distance from axis O-O)
Also, the length of the lever protruding from the cover 15 in the direction in which the lever is tilted can be freely set.

Therefore, the foldable shift lever device can be easily adapted to vehicle types having different seat and vehicle floor configurations.

Further, from the appearance, the fact that the shift lever 10 is foldable and the direction in which it is folded can be intuitively recognized. Moreover, the release knob 56 of the lock lever 52
Simply press down to release the torsion spring 50.
Since the upper lever portion 12 is automatically bent by the spring force, the shift lever bending operability is extremely good. At the same time, the durability of the shift lever 10 can be improved since no unreasonable force is applied to the joint portion (bending portion) of the shift lever 10. In addition, since the bent portion of the shift lever 10 is covered by the daytent plate 15, it is difficult to get clothes caught on the bent portion when the shift lever is in the tilted position, or to get dirty with the grease applied for lubrication. There is no fear.

6 and 7 show a foldable shift lever for an automatic transmission according to a second embodiment of the present invention. FIGS. 6 and 7 are diagrams corresponding to FIGS. 4 and 5 described above.

Note that in FIGS. 6 and 7, parts corresponding to those in FIGS. 4 and 5 are designated by the same reference numerals, and detailed explanation thereof will be omitted.

In this embodiment, the shape of the lock lever and the twisting direction of the spring attached to the lock lever are changed so that when the upper lever section is returned to its original upright position, the lock lever automatically enters the locked state.

As shown in FIG. 7, a protrusion 52b for preventing the lock lever from restoring is formed at the tip of the lock lever 52a. The protrusion 52b has an L-shaped cross section and extends downward beyond the bending position of the shift lever.

In addition, the release knob 56 and the detent plate 15
A compression coil spring 57a, which also serves as a torsion spring and is installed between the lock lever 52a and the lock lever 52a, always biases the lock lever 52a in the direction of contacting the stopper 60 (lock position). Note that the torsion spring force of this spring 57a is set to be sufficiently smaller than the spring force of the torsion spring 50 on the shift lever side.

Then, similarly to the embodiment described above, the shift lever 10
When the lock lever 52a is shifted to the P range and the release knob 56 of the lock lever 52a is pushed down, the lock lever 52a
The locked state is released, and the upper lever portion 12 is bent along the bending guide groove 51 by the spring force of the torsion spring 50 on the shift lever side. Then, the end surface 52c of the protrusion 52b of the lock lever comes into contact with the bent upper lever part 12, and the lock lever 5 is moved by the spring 57a.
2a is prevented from restoring, and the lock lever 52a remains in this state.

Next, when the upper lever part 12 is returned to its original upright state, the contact relationship between the protrusion 52b of the lock lever 52a and the upper lever part 12 is released, and the lock lever 52a is automatically returned to its original position by the spring 57a. Return. Then, the claw 54 of the lock lever 52a engages with the positioning hole 58 of the detent plate, and the lock lever 52a automatically enters the locked state.

In this embodiment, the lock lever 52a can be automatically returned to the locked state simply by returning the upper lever portion 12 to its original upright position.
There is no need to turn the release knob 56 of a, and the operability of returning the shift lever can be improved.

8 to 10 show a foldable shift lever device for an automatic transmission according to a third embodiment of the present invention.
8 to 10 are diagrams corresponding to FIG. 1, FIG. 3, and FIG. 4 described above.

In addition, in FIGS. 8 to 10, the above-mentioned FIG. 1,
Portions corresponding to FIGS. 3 and 4 are similarly designated by the same reference numerals, and detailed explanation thereof will be omitted.

In this embodiment, the direction in which the upper lever portion 12 is biased by the spring 50a is opposite to that of the previous embodiment, that is, the direction opposite to the bending direction of the shift lever.

That is, as shown in FIG.
A spring attachment shaft 12a is fixed in parallel to the axis Z-Z of the bolt 45. On the other hand, a spring mounting bracket 44a is also fixed to the housing 44 on the lower lever side. A coiled tension spring 50a is installed between the shaft 12a and the bracket 44a. Further, the fixing position of the shaft 12a to the upper lever part 12 is shifted to the right side in the figure from a plane T connecting the axis Z-Z of the bolt 45 and the spring attachment part of the bracket 44a, as shown in FIG. position, and the upper lever part 1
2 is bent so as to be located on the left side of the figure, as shown by the imaginary line. This constitutes a turnover spring mechanism. In this way, the upper lever portion 12 is urged by the tension spring 50a and comes into contact with the end surface of the cam hole 38a of the detent plate 15 on the driver's seat side (the upper end surface in FIG. 10).

Further, as shown in FIG. 10, the lock lever 52d provided in the middle of the bending guide groove 51 formed in the detent plate 15 has an L-shaped cross section and a protrusion 52e extending to the vicinity of the shift lever bending position. It's summery. Further, the claw 54a of the lock lever 52a and the positioning hole 58 of the detent plate 15 have been changed to the positions shown in the figure.

The bending operation of the shift lever 10 is
In the P range, push down the release knob 56 of the lock lever and bend the shift lever 10 along the bending guide groove 51 against the tension spring 50a. When the upper lever part 12 crosses the plane T shown in FIG. 8, it is automatically bent by the action of the tension spring 50a and stops at the position where it abuts against the lower end surface of the bending guide groove 51. Next, the lock lever 52d is rotated until it touches the stopper 60, and at that position, the user releases the hand and engages the pawl 54a with the positioning hole 58.
Note that the upper lever portion 12 that has been knocked down is prevented from restoring to its original upright state by the protrusion 52e of the lock lever 52d.

In this embodiment, the upper lever portion 12 that has been pushed down can be reliably held in that position by the protrusion 52e of the lock lever 52d. In other words, the upper lever portion 12 cannot be returned to its original position unless the lock lever 52d is operated to the unlocked position. Therefore, it is possible to provide a foldable shift lever with a structure that is superior in safety.

Although the present invention has been described in detail with respect to specific embodiments above, the present invention is not limited to the above embodiments, and includes various embodiments within the scope of the claims. Yes, for example, it can be applied to a type of shift lever where the push button on the shift knob of the shift lever is pushed down to disengage the daytent rod from the cam hole of the daytent plate, allowing the shift lever to perform gear shifting operations. It is. Further, a dust cover may be provided separately from the detent plate. Moreover, it is also possible to combine each of the above-described embodiments.

〔Effect of the invention〕

As explained above, according to the present invention, the folded shift lever can be set at any position where it does not get in the way when moving the seat, making it extremely easy to move the seat.

Further, even if a part of the body accidentally touches the shift lever while moving the seat, the transmission will not be activated inadvertently, making it safe.

Furthermore, the foldable shift lever device can be easily adapted to different vehicle types having different seat and vehicle floor configurations.
